JLPT N4 Vocabulary: What to Learn After N5

What the N5 to N4 jump actually looks like

When you finish N5, you have around 800 words and can handle basic greetings, numbers, simple present and past sentences, and core particles. That is enough to read a children's picture book slowly and understand a few lines of anime with heavy visual context. It does not feel like much, but it is a real foundation.

N4 pushes the cumulative count to roughly 1,500 words, adding approximately 700 new items. That number sounds manageable until you see what those words do to sentence complexity. N5 sentences are short and predictable. N4 sentences use subordinate clauses, cause-and-effect connectors, conditional forms, and abstract subjects. You go from "I ate sushi" to "if I had known the restaurant was closed, I would have eaten somewhere else." The grammar and the vocabulary grow together, which means learning N4 words in isolation from N4 grammar patterns will feel incomplete.

The kanji count also rises. N5 covers roughly 100 characters. N4 adds around 200 more, bringing the total to about 300 required kanji at that level. Many of the new kanji appear in compound words, which is where a lot of N4 vocabulary lives. This is different from N5, where single-kanji words are more common. Getting comfortable reading two-kanji compounds is one of the real skills N4 builds.

What kinds of words N4 adds

N5 vocabulary skews toward concrete, immediate, high-frequency items: body parts, food, family members, basic verbs of movement and existence. N4 expands into categories that feel less tangible but show up constantly in real conversation and reading.

More verbs, especially state and change verbs

N5 covered the action verbs you use to narrate what you do physically. N4 adds verbs that describe states, changes of state, and mental or emotional processes. Words like to decide, to become, to worry, to notice, to get used to. These are harder to picture than "to eat" or "to go" but they appear constantly in dialogue.

Adjectives and adverbs for nuance

N5 adjectives cover the obvious ends of the spectrum: big, small, hot, cold, good, bad. N4 adds the middle ground and the modifiers: strange, convenient, safe, various, especially, recently, at least, in a hurry. These words allow you to say something more precise than "it is good" or "it is bad," which is where real expression starts.

Abstract and daily-life vocabulary

N4 covers concepts that come up in everyday adult conversation: economy, society, opinion, reason, relationship, habit, experience, culture. None of these are exotic topics. They are what people talk about at work, at dinner, in news headlines. At N5 you can talk about what you did. At N4 you can begin talking about why you did it and what you think about it.

Compound kanji words

This is where N4 vocabulary starts to feel systematic in a useful way. Once you know the individual kanji meanings, compound words become partially predictable. The kanji for fire plus the kanji for mountain gives you volcano. The kanji for study plus the kanji for life gives you student. You will not always be able to guess, but you will guess right often enough that it starts to feel like reading a code rather than memorizing isolated items.

Representative N4 example words

These are not the official JLPT list. That list does not exist in public form. These are representative examples drawn from high-frequency N4 vocabulary that appears across multiple study resources and past test items.

• きめる (kimeru) - to decide
• なれる (nareru) - to get used to
• しんぱいする (shinpai suru) - to worry
• きがつく (ki ga tsuku) - to notice, to realize
• はじめて (hajimete) - for the first time
• べんり (benri) - convenient
• ふつう (futsuu) - ordinary, normal
• かんけい (kankei) - relationship, connection
• せいかつ (seikatsu) - daily life, lifestyle
• けいざい (keizai) - economy
• いけん (iken) - opinion
• りゆう (riyuu) - reason, cause
• けいけん (keiken) - experience
• しゅうかん (shuukan) - habit, custom
• いそぐ (isogu) - to hurry
• つづける (tsuzukeru) - to continue
• くらべる (kuraberu) - to compare
• おもいだす (omoidasu) - to recall, to remember
• ていねい (teinei) - polite, careful
• さまざま (samazama) - various, diverse

Notice that most of these are harder to picture than N5 words. You cannot draw "convenient" the way you can draw "apple." This is why N4 vocabulary demands more review repetition per word. Concrete words stick faster because you can associate them with a physical image. Abstract words require you to see them in context multiple times before they become automatic.

Kanji at N4

The roughly 300 kanji at N4 level introduce a shift in how you should think about kanji study. At N5, it was reasonable to learn characters one by one because many appeared as standalone words. At N4, the payoff comes from recognizing patterns across compound words.

A practical approach: when you encounter a new N4 vocabulary word that contains kanji, look at each character individually. What does each one mean on its own? How do they combine? Even a rough answer to those two questions gives you a mental hook that pure pronunciation drilling does not. You do not need to memorize stroke order unless handwriting is a goal. Reading recognition is what the test requires.

Do not rush kanji. A common mistake at N4 is trying to power through all 300 new characters in a few weeks using a kanji-only approach, separate from vocabulary. This fragments your learning. You end up knowing that a character exists without knowing how it is used. Learn kanji through the words they appear in, not as abstract symbols to collect.

How to study N4 vocabulary without burning out

The N5-to-N4 transition is where a lot of learners stall. Not because N4 is impossibly hard, but because the pace that worked at N5 does not scale. At N5 you might have learned 20 new words a day without much trouble. At N4, 20 new abstract words a day is exhausting, and if you fall behind the review queue builds up until opening your flashcard app feels like opening a bill you cannot pay.

Chunk by topic or function, not by list number

Rather than working through an alphabetical or frequency-ranked list from top to bottom, group N4 words by what they do. Spend a week on change-of-state verbs. Then a week on daily-life nouns. Then adjectives for degree and nuance. Themed sessions give the words a context that helps them stick, and they make each week feel like a coherent unit rather than a random batch of items.

Use spaced repetition and trust it

Spaced repetition is particularly valuable at N4 because the words require more exposure before they become automatic. A system like FSRS adjusts review intervals based on how confidently you recall each card. This means hard abstract words get reviewed more often without you having to decide that manually. If you study consistently, the algorithm surfaces the right words at the right time.

The trap is adding too many new cards per day. Ten to fifteen new N4 words per day is sustainable for most people. Twenty-five is not, because the review load accumulates faster than you can clear it. Slow down the new card intake before you slow down the review sessions.

Keep the N5 base warm

Do not stop reviewing N5 vocabulary when you move to N4. You do not need to spend as much time on it. With spaced repetition, mature N5 cards might only need a few minutes of review per week. But abandoning N5 review entirely leads to regression. Months later you will encounter a basic N5 word and draw a blank. That kind of regression is demoralizing and wastes time you spent building the foundation.

Inku ships a 391-card N4 deck built on high-frequency N4 vocabulary, designed to sit alongside the 515-card N5 deck in the same review queue. Both decks run through the same FSRS scheduler, so your N5 maintenance and N4 expansion happen in a single session rather than two separate apps or decks you have to manage manually.

Add passive exposure alongside active review

Flashcards build recognition. Reading and listening build fluency. At N4 level, simple Japanese content starts to become accessible if you are patient with it. Graded readers at N4 level, NHK Web Easy articles on topics you already know, or simple slice-of-life manga give you the words in context, which deepens the neural pathway that flashcards start. Aim for at least a few minutes of passive exposure daily in addition to your card sessions.

Common mistakes when moving from N5 to N4

These patterns show up often enough that they are worth naming explicitly.

Rushing the kanji

Trying to front-load all 300 new kanji before studying vocabulary is a common mistake. It creates a two-month delay before you feel like you are actually learning Japanese again. Worse, kanji studied in isolation without word context fades quickly. Learn the kanji through the words, not before them.

Ignoring verb conjugation

N4 introduces several new grammar forms that change how verbs look. Te-form, conditional forms, volitional form, causative, passive. If you focus only on adding new vocabulary without learning these conjugations, you will recognize words in their dictionary form and fail to recognize the same word in a sentence. Vocabulary and grammar have to grow together at this level.

Abandoning N5 review

Already mentioned above, but worth repeating because it is one of the most common and most costly mistakes. Do not let the N5 deck go cold. A five-minute maintenance session several times a week is enough to keep mature cards alive.

Studying from a single source

No single vocabulary list, app, or textbook covers N4 perfectly. Different sources weight words differently. If you only use one source, you will have gaps. Use your primary flashcard deck as the spine, and let graded readers or listening practice fill in the surrounding context.

A realistic timeline

Most people studying 15 to 20 minutes a day with consistent spaced repetition build a solid N4 vocabulary base in three to six months. That range is wide because it depends heavily on how much reading and listening you do alongside the flashcard work, and how familiar you already are with the concepts N4 words describe in English or your native language.

Month one is usually slow. Abstract words resist sticking, and the review load for N5 maintenance plus new N4 cards is heavier than you expect. Push through this phase without increasing your new card count. Let the reviews settle into a rhythm.

Months two and three are when the compound kanji logic starts to click. You will notice that you can partially predict the meaning of words you have never seen before. That is a real shift in how you are processing the language, not just accumulating a larger list.

By month four or five, if you have been consistent, the N4 deck will feel mostly familiar. New cards will still take effort, but the base is solid. This is when adding grammar practice and reading at N4 level makes the vocabulary feel alive rather than abstract. The goal is not just to recognize 1,500 words in isolation. It is to read a sentence, understand it without translating in your head, and move on.

There is no shortcut through this phase. But there is a pace that is sustainable without burning out, and that pace is slower than most learners start out trying. Ten to fifteen new words a day, consistent review, passive exposure where you can fit it in, and patience with the abstract words that take longer to stick. That combination gets most people through N4 vocabulary in a reasonable time frame without needing to restart from zero.
